What is the ruling of Islamic law regarding living in apartment buildings that were seized and had their contents stolen during the revolution in Libya?

The prohibition of theft, usurpation, and encroachment upon people's wealth is well-known. Money acquired in this manner is not permissible for its owner; rather, he must repent to Allah and return it to its rightful owner. Whoever knows the reality of this usurpation is not permitted to reside in these dwellings unless their owner grants permission and they reach a mutual agreement.
